人们高度重视公平，人们愿意付出个人代价，以防止他人从不公平行为中受益。公平性判断会受到群体一致性的影响吗？一种新的理论认为，当我们的个人身份与一个群体融合时，我们会倾向于内部群体，而贬低竞争对手的外部群体成员。虽然mPFC已分别牵连在组成员和公平处理，目前还不清楚是否组对齐影响内侧前额叶皮层（mPFC）的活动，以响应公平。在这里，我们研究的贡献，不同地区的mPFC处理从内组和外组成员和测试是否其反应不同，这取决于如何融合，我们是一个内组。受试者进行了几轮最后通牒游戏，在接受功能性磁共振成像（fMRI）的同时，同一足球队的支持者（内组）、最激烈的竞争对手（外组）或中立的个人提供了公平或不公平的资金分配。引人注目的是，人们愿意承担个人成本，以防止外群体成员从不公平和公平的提议中受益。背侧和腹侧（VMPFC）部分的mPFC的活动反映了公平性和组成员之间的相互作用。特别是VMPFC活动是一致的，它编码一个人的融合到一个组，与组成员的相互作用的公平性相关的程度，响应者的身份融合到内组。因此，融合对社会行为的影响似乎与VMPFC中的处理有关。
People are highly attuned to fairness, with people willingly suffering personal costs to prevent others benefitting from unfair acts. Are fairness judgments influenced by group alignments? A new theory posits that we favor ingroups and denigrate members of rival outgroups when our personal identity is fused to a group. Although the mPFC has been separately implicated in group membership and fairness processing, it is unclear whether group alignments affect medial prefrontal cortex (mPFC) activity in response to fairness. Here, we examine the contribution of different regions of the mPFC to processing from ingroup and outgroup members and test whether its response differs depending on how fused we are to an ingroup. Subjects performed rounds of the Ultimatum Game, being offered fair or unfair divisions of money from supporters of the same soccer team (ingroup), the fiercest rival (outgroup) or neutral individuals whilst undergoing functional Magnetic Resonance Imaging (fMRI). Strikingly, people willingly suffered personal costs to prevent outgroup members benefitting from both unfair and fair offers. Activity across dorsal and ventral (VMPFC) portions of the mPFC reflected an interaction between fairness and group membership. VMPFC activity in particular was consistent with it coding one's fusion to a group, with the fairness by group membership interaction correlating with the extent that the responder's identity was fused to the ingroup. The influence of fusion on social behavior therefore seems to be linked to processing in the VMPFC.
